Abstract: Recent advances in CeO₂ catalyst support are introduced. It is reported that the unique ability of transferring oxygen makes CeO₂ a good catalyst support in oxidation，methanol cracking，steam reforming and water gas shift (WGS) reaction，methanol decomposition and reduction of nitrogen oxides. Large specific surface area CeO₂support can be prepared by the sol-gel method and supercritical drying method. The main factor of restricting its practical application is the poor thermal stability and mechanical strength.
